Security features may be required for
some services, such as banking services
or online shopping. For such
connections you need security
certificates and possibly a security
module, which may be available on your
SIM card. For more information, contact
your service provider.
To view or change the security module
settings, or to view a list of authority or
user certificates downloaded to your
device, select

Important: Even if the use of
certificates makes the risks involved in
remote connections and software
installation considerably smaller, they
must be used correctly in order to
benefit from increased security. The
existence of a certificate does not offer
any protection by itself; the certificate
manager must contain correct,
authentic, or trusted certificates for
increased security to be available.
Certificates have a restricted lifetime. If
"Expired certificate" or "Certificate not
valid yet" is shown, even if the
certificate should be valid, check that
the current date and time in your device
are correct.
Before changing any certificate settings,
you must make sure that you really trust
the owner of the certificate and that the
certificate really belongs to the listed
owner.
